2 Claims.

This invention relates to means for assembling core members on arbors, and has more particularly reference to such arbors and core members as are to be used in slitting and winding ma- Ch1neS-- The main object and feature of the invention is to provide for the ready and quick assembling of core members and arbors extraneously of the machine in which they are to be used.

This application is a division of one filed September 10, 1937, Ser. No. 163,190, and of another filed May 11, 1938, Ser. No. 207,258.

In the accompanying drawings the invention is disclosed in a concrete and preferred form in which:

Fig. l is a top plan view of a spool loading box that may be utilized in connection with the present invention, parts being broken away and in section;

Fig. 2 is an end elevation of Fig. 1, parts being broken away and in section;

Fig. 3 is a vertical sectional view substantially on the plane of line 33 of Fig. 1, parts being broken away;

Fig. 4 is a vertical sectional view substantially on the plane of line 4-4 of Fig. 1;

Fig. 5 is a transverse section of one of the empty spools or core members in position on the arbor prior to its locking engagement therewith;

Fig. 6 is a similar section showing the interlocking connection between the spools or corev members and the supporting arbor;

Fig. '7 is a vertical longitudinal section of Fig. 6; and

Fig. 8 is an enlarged fragmentary section of the arbor sleeve and the spool or core member locking device.

Referring to the drawings, spool-supporting or winding arbors are provided, each of said arbors, in the form here illustrated, consisting of an inner shaft 54, an outer sleeve 43 within which the shaft is turnable, and a tapered band or thimble 54b which retains the sleeve against axial displacement on the shaft and facilitates the insertion of the arbor into the winding cores which are here shown in the form of spools 50 arranged in predetermined laterally-spaced order. For the purpose of releasably locking the spools to the arbor in any desired arrangement, suitable means are provided such, for example, as that shown in Figs. 5, 6, 7 and 8. As there shown, sleeve 48 is provided with opposite series of holes or sockets 5! having portions of the surrounding metal upset by a peening operation to form flanges 5la (Fig. 8) for limiting the outward displacement of spool-engaging locking members, here shown as balls 52 disposed in said holes or sockets. For limiting the inward movement of balls 52, shaft 54 is provided with oppositely presented flattened surfaces 54a, the construction being such that .1 in the relative positions of the parts shown in Fig. 5, the spools may be readily placed on and removed from the arbor while, in the positions of the parts shown in Fig. 5, and in Fig. 6, the spools are locked to the arbor by permanently deforming the sheet material of the spools by the protrusion of balls 52. For the purpose of facilitating these operations and more especially for enabling the spools to be mounted on the arbor in a predetermined laterally-spaced order in a rapid and accurate manner, a loading box 49 is provided in which stationary spool supports 53, in the form of open bearings to engage the outer surfaces of the spools, are arranged in the desired predetermined order in which the spools are to be mounted in a slitting or winding machine. The spools having been placed on said supports, the arbor is next inserted endwise through said spools until an enlargement or collar 60 near its outer end enters a recess 6| in the side wall of loading box 49 with the arbor resting in coaxially alined bearings 62 and 63 in the opposite side walls of the loading box. If desired, pivoted latches 60a can be used to hold the arbor down in bearings 62 and 63. Keyed to the shaft 54 is a spur gear 55' which meshes with a larger spur gear 56 which turns on a fixed stub shaft mounted on said side wall of the loading box. A lever 51, which is acted upon by a spring 58 that tends to retain it in normal position against a stop pin 59, is rigidly connected to gear 56 for turning gear 55 and shaft 54 from its position shown in Fig. 5 to its position shown in Fig. 6. During this movement, the sleeve is held against turning by means of a fixed pin 64 in recess 6!, said pin being then disposed in a peripheral notch 55 (Fig. 2) in enlargement Bil of the sleeve. As shown in Figs. 1 and 2, enlargement 60 is provided with a peripheral groove 68 extending approximately 90 degrees about the axis of the sleeve. A pin 6? presented into this groove from gear 55, is moved in a counterclockwise direction from its position shown in Fig. 2 to the upper end of said groove by the rotation of shaft 54 between its successive positions with respect to sleeve 48 shown in Figs. 5 and 6 respectively. Keyed to the outer end of shaft 54, is a spur gear 66 by means of which the arbor is rotated in the windng mechanism. According to the embodiment of the invention 55 .by lever 5'1.

shown in the drawings, two groups of empty spools are shown at the right in Figs. 1 and 2, the coaxially arranged spools on one arbor being disposed in staggered relation to the similarly arranged spools on the other arbor. After lever 51 on the right has been depressed to impart a quarter turn in a clockwise direction (Fig. 2), to lock the core members to the spools, both groups of spools with their arbors are removed from the loading box and are in readiness to be placed in the upper and lower spooling mechanisms respectively of the winding machine. It will be understood that, when cores 5!! are locked to sleeve 48 by the turning movement of shaft 54, pin 6! abuts against the end of slot 68, and that the parts remain in this position when the arbor is inserted in the winding machine. Therefore, when power is applied by the winding machine to gear on shaft 54, the rotation of the latter will drive sleeve 48 through 61 and 68 in unison with said shaft or, forthat matter any subsequent rotation of shaft 54 in the same direction will drive sleeve 48 in unison therewith.

Upon completion of the spooling or winding operation, the arbor or arbors which carry the filled spools are removed from the winding mechanism and placed in bearings 62 and 63 shown at the left in Fig. 1 with notches 65 in enlargements (ill of the sleeves in engagement with the fixed pins 64, the pins 61 on the spur gears being disposed at the upper ends of arcuate recesses 68. A depression of left-hand lever 51a produces an unlocking movement of shafts 54 within sleeves 48, said unlocking movement being substantially similar to but in a reverse direction with respect to the locking movement produced The balls 52 are now relieved from an outward displacing pressure due to the clearance aiforded to them by flattened surfaces 54a. The arbors are then retracted endwise from the spools which are stripped therefrom by a side wall of the loading box. It is clear from the foregoing description that the empty spools are rapidly and easily arranged in predetermined order in one side of the loading box wherein they are simultaneously loaded upon arbors which may be quickly and easily mounted in the winding mechanism and expeditiously wound, after which the arbo-rs are removed from the winding mechanism and the wound cores or spools are stripped from the arbors to fall into the other side of the box from which they may be taken and wrapped for the market.

. I claim:

1. An arbor including: an outer sleeve, an inner shaft, a gear carried by the shaft, a pin and circumferential slot connection between the gear and sleeve to permit the gear to rotate the shaft with respect to the sleeve to a limited extent, and a second gear on the shaft to drive the shaft and sleeve in unison through the pin and slot connection after the pin has reached the end of the slot.

2. The combination of a sleeve, an inner shaft extending therethrough, one or more core members mounted on the sleeve, a locking device to lock the core member or members on the sleeve by a limited turning movement of the shaft within the sleeve, a connection between said means and the sleeve to permit a limited but to prevent a continuous turning movement of the shaft within the sleeve, whereby subsequent rotation of the shaft drives the sleeve through said connection after the core member or members are in locked position.
